Abstract

Die Erfindung betrifft ein Verfahren und eine Windenergieanlage mit einem Windrotor (3) zum Antreiben eines Asynchrongenerators (4) zur Abgabe elektrischer Leistung an einen Transformator (9). Die Erfindung sieht vor, dass der Transformator (9) mit zwei Primärwicklungen (91, 92) versehen ist, und der Generator (4) über einen Umschalter (8) je nach Betriebsart mit einer der beiden Primärwicklungen (91, 92) verbunden wird. Damit kann eine Verschiebung der Betriebskennlinie der Windenergieanlage erreicht werden. Somit kann die Kennlinie nach unten hin zu Schwachwindbedingungen verbessert werden, ohne dass dafür der herkömmlicherweise erforderliche Zusatzaufwand anfällt.
